I love these posts, I look forward to the follow up when you are "unjustly" banned for boxing.

SHM/Warrior/Druid

slow and thorns do a lot of work and you have enough healing and regen to live through most ugly pulls.

War + Rog + Clr is my favorite trio. Have your dad play the rogue or warrior. Have your best player on the cleric. A good cleric can memblur, single pull, cc, everything you really need.
